Installation Preparation

Site Considerations

Considering the following helps you plan an acceptable operating environment for the chassis, and avoid

environmentally-caused equipment failures.

• Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment

• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively

• Always follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge

Power Supply Considerations

See

Power Supply, on page 16
